Now the wastewater ratio of some water purifiers is too high, I want to ask how about Wanhe s water

As long as the water purifier that produces wastewater, there is no one with a low wastewater ratio, unless the filtration effect is poor, this is really difficult to choose;

It is necessary to have a good filtration effect and less wastewater, which cannot take into account the ......

The water purifier is filtered (or ion exchange) through the membrane, small molecules can be passed, large molecules are throttled in the membrane, and the filtered water contains less ions and impurities. Only the membrane has trapped impurities and macromolecules, when the interception is more, the membrane flux decreases, and even when the resistance is equal to the inlet pressure, the water cannot pass through, and there is no water outflow at the outlet end.

Therefore, it is necessary to backwash the membrane from the outlet end with high-pressure water under a certain pressure before this, and only then the backwashed water is called wastewater, and the rest of the time is tap water, but the number of molecules and total dissolved solids is just that. Urban tap water can meet the sanitary standards of drinking water, and the general tap water residence time is more than 48 hours before it is considered to be not in line with the health standards.

Because this is the basic volatilization of residual chlorine in the water, it does not play a role in killing viruses, and bacteria and algae may breed. The water in the water purifier that does not stay for more than 48 hours is in accordance with the sanitary standards. Generally, the backwashing water purifier is considered to be backwashed according to the pressure, and there is no untimely discharge, and if it is not used for a long time, it is necessary to put water for a while and use it for several treatment cycles.

Household water purifier without backwashing, due to the increase of the flux of the filter material with the use of time, the resistance becomes larger, the water passes more and more slowly, when the resistance reaches a certain value, there will be water residue in the filter material, generally when the water residence time in the filter material exceeds 48 hours, the antibacterial effect in the water disappears, bacteria and algae begin to breed, this phenomenon is difficult to find according to the inlet water quality or different use conditions, if the filter material can not be regenerated or replaced in time, it is possible that the water has been polluted, it is not suitable to continue to use.

In order to ensure water safety, it is recommended to use city tap water or a water purifier with backwashing.

Purchase high performance** ratio.

1. The structure of the water purifier is different, and the water purification effect is also different. Generally speaking, the structure of the primary filtration water purifier is simple, mainly activated carbon, its filtration capacity is limited, and it can only be used for coarse filtration, and the filtered water is best heated and boiled for drinking. Most of the first-level filtration water purifiers are low-grade water purification products, and the price of each unit is between more than ten yuan and 150 yuan.

2. Multi-stage filter water purifier. This kind of water purifier has two stages of coarse filtration and one set of fine filtration, and the fine filtration mostly uses hollow fiber filter element, and the filtered water can be directly drinkable. Multi-stage filter water purifier is a mid-range water purification product, each priced between 300 yuan and 500 yuan, which can be accepted by the working class and used more by families.

3. UF ultrafiltration nanofiltration membrane water purifier is composed of multi-stage prefiltration and ultrafiltration membrane, which can intercept most of the bacteria and harmful substances, and is the most commonly used direct drinking water purification device with the most common separation and filtration effect on the market, while retaining the mineral trace elements that are beneficial to the human body, and then using the advantages of KDF and activated carbon to effectively inhibit the breeding of bacteria and fungi in the water and remove different colors and odors, so as to ensure that the filtered water can be used safer and healthier. Moreover, the water production is relatively large, and the wastewater discharge is small, so that it is faster and more square when used in the family kitchen.

Yes, you don't have to wait a long time. It is a popular consumer product, and the price of each unit ranges from 200 yuan to 5,000 yuan according to different requirements. The wastewater ratio has a lot to do with the RO membrane inside, and the wastewater comes from tap water.

According to the design principle of the membrane, the higher the TDS value of the raw water, the more wastewater needs to be used to flush the RO membrane, that is to say, the higher the proportion of wastewater, and there is more wastewater than good water when making water.

1. Proportion of common wastewater.

Wastewater ratio refers to the volume ratio of wastewater discharged by a water purifier to the pure water produced per unit of time. The wastewater ratio of the traditional 50g water purifier is 3:1, that is, 3 parts of wastewater need to be discharged to produce one piece of pure water.

The water purifier will produce a large amount of wastewater at the same time as making water, and each pure water will produce at least 3 parts of wastewater (up to 8 parts in winter or in northern areas), which is the so-called wastewater ratio of 1:3.

2. Adjust the wastewater ratio method.

1) The RO membrane of reverse osmosis is aging, and the pure water production decreases, resulting in a large increase in the amount of wastewater. A new RO membrane is required.

2) If the wastewater ratio is too conductive or the flushometer is not closed tightly, replace the corresponding parts.

3) The high-pressure switch or check valve is damaged, so that the water storage tank is full and cannot be shut down and continues to produce excess wastewater. In some cases, the machine will be restarted repeatedly. Replace the appropriate part.

Because the water purifier uses the principle of filtration, the good water filtered by the water purifier is less.

The system can adjust the amount of water produced from a few to a few points.

The water purifier wastewater ratio refers to the ratio of the amount of wastewater treated by the water purifier to the amount of pure water produced. This ratio is usually expressed as a percentage, for example, a wastewater ratio of 80% means that the water purifier treats 100 litres of water, producing 20 litres of purified water and at the same time producing 80 litres of wastewater.

The size of the water purifier's wastewater ratio depends on factors such as the type of water purifier, brand, filtration technology, and water quality. The traditional reverse osmosis water purifier wastewater is relatively high, usually between 3:1 and 4:

1, i.e. treating 1 liter of water will produce 3 to 4 liters of wastewater. The new water purifier technology, such as nano filter element, ultrafiltration membrane, etc., can reduce the wastewater ratio to less than 1:1, that is, treating 1 liter of water will only produce less than 1 liter of wastewater.

The ratio of water purifier to wastewater not only affects the efficiency of water resource utilization, but also has a certain impact on the environment. Therefore, when choosing a water purifier, you should comprehensively consider factors such as water purification effect, waste water ratio, maintenance cost, etc., and choose a water purifier that suits you.

The wastewater rate of the water purification cracker is between 1:3 and 1:7.

Depending on the manufacturer's product and the quality of the water, the wastewater rate will also vary. For every 1 bucket of pure water that comes out of the water purifier, 3 to 7 buckets of tap water are wasted.

How the water purifier works.

1. Microfiltration membrane, microfiltration membrane removes all kinds of visible dust and impurities in tap water. These particulate matter comes from aging pipes, rust, secondary pollution of roof tanks, etc.

2. Compressed carbon, compressed carbon removes chlorine and organic impurities, such as harmful pesticides. It also absorbs odors, colors and odors from organic compounds in the water, which are by-products of tap water disinfection.

3. Ultrafiltration membrane, ultrafiltration membrane can remove bacteria, viruses and spores and other substances in water.

4. Filter element life indicator, the device is designed for the gear structure inside, with the passage of the water, the gear rotation mold rotates to make an axial movement inside until the water outlet is blocked, and the water flow can not pass, that is, the total amount of water through the water purifier is calculated through the designed stroke, so as to ensure that the water is safe. <>

There are several reasons why the water quality of the water purifier may be worse than that of tap water:

1.Different filtration effects: Different types of water purifiers use different filtration technologies and types of filter elements, so the treatment effect on water quality will also be different.

Some low-cost or low-quality water purifiers may only remove some impurities and odors, but cannot completely remove harmful substances, resulting in water quality that is not as good as tap water.

2.Aging or untimely replacement of the filter element: The filter element of the water purifier needs to be replaced regularly, if the filter element is used for too long or not replaced in time, it may lead to the filtration effect of the filter element to decrease, thus affecting the water quality.

3.Improper maintenance: The maintenance of the water purifier is also very important, if it is not cleaned correctly according to the instructions and the eggplant orange is not maintained, it may lead to the breeding of bacteria or pollutants inside the water purifier, which will affect the water quality.

4.Different water sources: tap water is treated by the water plant to the residents, and the water source of the water purifier may be tap water, well water, groundwater, etc., and the quality difference of the water source will also lead to the water quality of the water purifier is different from the tap water.

Therefore, choosing the right water purifier, replacing the filter element regularly, maintaining the water purifier correctly, and paying attention to the quality of the water source balance are all important factors to ensure that the water purifier has good water quality.

If it is a newly installed water purifier, it is best to contact the Kaishu brand after-sales service first, and check whether the filter element is not installed well or the water purifier is a problem.

If the water purifier is installed for a period of time, the probability of the person who is slow down is to replace the filter element.

Accumulated impurities nourish microorganisms.
